SPECIFICATION forming part of Letters IPatent No. 423,653, dated March18, 1890.

Application filed November 25, 1889- Serial No. 331,480' (No model.)

To all whom it may concern:

Be it known that I, MILTON ABRAMS, a citi-.

zen of the United States, residing at'Indianapolis, in the county ofMarion and State of Indiana, have invented anew and useful Improvementin Feed-Tater Heaters and Puri fliers, of which the following is aspecification.

My invention relates to an improvement in that class of devices forheating and purifying the Water supplied to steam-boilers in from theengine-cylinders by the exhauststeam from entering and commingling withthe feed-water in the heater; and, second, to

more thoroughly and completely separate the magnesia and lime compoundsand other 1111- purities from the feed-water, all as hereinafter. fullyexplained.

The accompanying drawings illustrate my invention.

Figure 1 represents a central vertical section of my device. Fig. 2represents a plan at the line a, Fig. 1. Fig. 3 represents a section onthe line b, Fig. 2, and below the line a, Fig. 1.

A is a cylindrical tank having a closed top, and formed, preferably, ofboiler-iron. In the lower part of tank A is a horizontal annularpartition B and a circular partition 0, which is riveted 'at the bottomto the tank and at the top to the inner edge of the annular partition B,thus forming a central well D. A portion of the annular space betweenthe Walls of the tank and the circular partition 0 is separated from therest by vertical partitions e and f, which rise above the horizontalpartition B and join at the top, thus forming, with the front plate G,an inclosed chamber H. The exhaust-steam frointhe engine enters chamberH through the inlet-pipe I and passes out through the bent pipe J, sothat it is discharged directly downward into the central well D. For thepurpose of discharging from the exhaust-steam the oil and grease broughtover from the engine and held in mechanical suspension the arrangementof the inlet-pipe I and discharge-pipe J is such that the central welland the Walls of the tank is divided by a series of vertical partitionsland m into a series of communicating compartments a, the first of whichcommunicates through an opening 0 in the partition C with the centralwell D. The arrangement of these 7 vertical partitions is such thatthere is a space over the top of the partitions Z, as seen indottedlines, Fig. 1, and a space under the partitions on, and they arearranged alternately so that Water passes from the top of the firstcompartment n and from the bottom of the next compartment, and so on tothe lastcompartment from which the feed-Wat er is drawn through the pipe19 for the supply of the boiler.

is an overflowi e arran ed in the last P P s of the compartments a. Eachcompartment is provided with a drain-pipe 7, closed by a suitable valveand a hand-hole s.

The upper part of the tank A is filled with a series of shallow panstand u, pans u having a central opening a. The pans are arrangedalternately, so that the supply of water entering through thesupply-pipeW at the top of the tank overflows at the center of the first pan and atthe edges of the next, and so on alternately until it falls onto theslightlyinclined annular partitionB and drains into the central Well D.y

Y is the escape-pipe, through which the uncondensed steam escapes.

'In operation water is pumped from the well or other source of supplythrough the supplypipe WV into the upper one of the series of pans, andfrom thence flows over the series of pans, as before explained, to thecentral well D. Exhaust-steam from the engine entering chamber IIthrough pipe I is projected against the opposite wall of the chamber and'drops in the chamber the grease and oil and a portion of the watercarried therein, and

' thenpassing through bent pipe J is projected downward into the centralwell D, thus heating the water therein, and then passes upward,circulating around and between the pans t and u and heating the watercontained in and overflowing. from the pans. A large portion of thesteam is condensed and-flows downward with the feedwater, and theremainder passes off through the escape-pipe Y. The heated water fromthe wellD passes through the opening 0 to the first compartment n, andfrom thence over partitions Z and under partitions m successively untilthe last compartment is reached, from whence it is drawn out through thefeed-water pipe 10. Those elementsin thewater-supply which ordinarilyform the harder portions of the scale in the'boiler are deposited on thepans't and a, while the lighter magnesia and lime compounds containedtherein, which in other heaters and purifiers is partially separated bypassing the water through hay or other filtering material, is depositedas a sediment in the central well and the compartments n, in which thewater stands comparatively still and under favorable conditions for thedeposition'of chamber to the waterspace of the tank, all being arrangedto co-operate substantially as specified, whereby the grease carried insuspension in the steam is precipitated before entering the water-space,as set forth.

2. In a feed-water heater, the combination of a water-tank, an inclosedchamber separated from the water-space thereof, a steam- ;supply pipeleading into said chamber from substances suspended in the steam areprecipitated, substantially as set forth.

3. In a feed-water heater and purifier, the combination, with thewater-tank, ot' the central well formed in the lower part of the tank, aseries of compartments arranged around said well, one of whichcompartments coinmunicates with the well, and the compartmentscommunicating with each other in succession at the top of one and at thebottom of the other, the steam-supply pipe arranged to enter the tankabove the central well, thewater-supply pipe also arranged toenter thetank above said well, and the water-discharge pipe leading from the lastcompartment, all arranged to co-operate substantially as specified,whereby the water in the well is heated by the steam and is Withdrawnfrom the tank through a series of settling-compartments, substantiallyas specified.
